"This scholarly resource is an important contribution to the literature of the history of science, providing descriptions of many instruments that are overlooked in other books." -- Booklist"The first reference book to address the immense historical range of instruments and also the first to consider application, innovation, and costs. Its emphasis on twentieth-century devices and disciplines makes it especially valuable to students and scholars of modern science and technology, and the beauty of some of the antique instruments makes it a valuable guide for collectors, dealers, and curators." -- The ChemicalEducator"The editors state: "This volume is intended to communicate clearly to a wide audience." This goal has been achieved, as the work is very readable, with little specialized jargon. This encyclopedia comes highly recommended, especially for academic/research or large public libraries. In addition, anyone who has an interest in the subject would benefit. And the price is modest for an illustrated 700-page reference book." -- E-Streams"This book will be of greatest value to students of the history of science. The short bibliography at the end of each subject is useful, and in many cases one of the reference works cited was written by the contributor..." -- Nature"...it is hard to put down once you've started reading. It is an excellenct reference work that should find a place on the shelves of all science and technology museums and libraries." -- Rittenhouse"Instruments of Science will undoubtedly prove a useful reference work..." -- Johns Hopkins University Press
